/**
 * Note: sub-menu only appear when route children.length >= 1
 * Detail see: https://panjiachen.github.io/vue-element-admin-site/guide/essentials/router-and-nav.html
 *
 * hidden: true                 当设置 true 的时候该路由不会在侧边栏出现 如401，login等页面，或者如一些编辑页面/edit/1(默认 false)
 * redirect: 'noRedirect'       当设置 noRedirect 的时候该路由在面包屑导航中不可被点击
 * alwaysShow: true             当你一个路由下面的 children 声明的路由大于1个时，自动会变成嵌套的模式--如组件页面
                                只有一个时，会将那个子路由当做根路由显示在侧边栏--如引导页面
                                若你想不管路由下面的 children 声明的个数都显示你的根路由
                                你可以设置 alwaysShow: true，这样它就会忽略之前定义的规则，一直显示根路由
 * name: 'router-name'          设定路由的名字，一定要填写不然使用<keep-alive>时会出现各种问题
 * meta: {
        roles: ['admin', 'editor']      设置该路由进入的权限，支持多个权限叠加
        title: 'title'                  设置该路由在侧边栏和面包屑中展示的名字
        icon: 'svg-name'                设置该路由的图标，支持 svg-class，也支持 el-icon-x element-ui 的 icon
        noCache: true                   如果设置为true，则不会被 <keep-alive> 缓存(默认 false)
        breadcrumb: false               如果设置为false，则不会在breadcrumb面包屑中显示(默认 true)
        affix: true                     如果设置为true，它则会固定在tags-view中(默认 false)
        activeMenu: '/article/list'     当路由设置了该属性，则会高亮相对应的侧边栏。
                                        这在某些场景非常有用，比如：一个文章的列表页路由为：/article/list
                                        点击文章进入文章详情页，这时候路由为/article/1，但你想在侧边栏高亮文章列表的路由，就可以进行如下设置
